feat(core): add progressbar, alert and combobox roles to getByRole

[gmegidish]

Summary

Follow-up to #160 / #186. Adds the three roles from Playwright's role list that have real native widgets on mobile:

Role	iOS	Android
progressbar	ProgressIndicator, ActivityIndicator	ProgressBar
alert	Alert, Sheet	—
combobox	Picker, PickerWheel	Spinner, AppCompatSpinner

Role is derived from ROLE_TYPE_MAP, so the type picks these up automatically. The rest of the ARIA list (treeitem, menubar, rowheader, …) has no native equivalent and is intentionally left out.

Docs role tables updated to match.

Credit

Builds on the ROLE_TYPE_MAP / derived Role design by @Dhakshath11 in #186 and the RFC in #123. Original request by @vethman in #160.

Test plan

• npx playwright test packages/mobilewright-core/src/query-engine.test.ts — 117/117 passing (3 new)
• npm run lint
• Real-device smoke

Walkthrough

The query engine now supports progressbar, alert, and combobox mappings for Android and iOS native controls. Tests cover these mappings and exclude unrelated widget types. Locator and CLI documentation now list the new roles and their corresponding native controls.

Priority: ⬇️ Low

Merge Risk: 🟠 High · up to 19134

The new roles do not work for the advertised iOS controls. Extend the upstream allowlist and correct the contradictory documentation before merging.

Remove the stale no-role examples.

This note says that Android Spinner and iOS Picker have no role mapping. The tables above now map both controls to combobox. Remove these examples or replace them with controls that remain unmapped.
